the sexual organs and also narrow the way to the honey. The 

 Hymenopteron Scolia aureipennis, Lep., was seen twice on the 

 flowers (Plassey, 3-ix-07) sucking honey ; and the Hymenop- 

 tera Eumenes conica, F., and Sphex lobatus, L., were seen doing 

 the same in Calcutta (2-xi-01), the latter diligently. 



Toddalea aculeata, Pers., was found to be visited by a 

 small bee at Pongging in the Abor Hills The anthers do not 

 touch the stigma at all. 



Aegle Marmelos, Correa, has very sweet-scented flowers 

 which attract a considerable variety of insects (Dacca, 2- 

 vi-11). 



Zizyphus Jujuba, Lamk., by reason of its abundant free 

 honey attracts a variety of visitors. The flowers are at first 

 male, and later female, just as those of the Euonymus figured 

 in Note No. 7. They lie close to one another ; and neighbours 

 are more likely to be in different stages than in the same, so 

 that fertilisation of neighbouring flowers can be accomplished 

 easily. Their duration is about three days. Polystes hebraeus, 

 F., and another Hymenopteron have been seen as visitors, 

 an ant, a small Dipteron and a beetle (Calcutta, 15-ix-0l) ; 

 the same species of Polystes and other insects were seen on the 

 flowers at Nandurbar, Tapti valley, sucking honey (27-ix-09). 



Zizyphus nummularia, W. and A., which is very similar, 

 to the last, was seen visited by the Hymenopteron Megaspis 

 crassus, F., at Nandurbar (27-ix-09). 



Vitis trifolia, Linn., is very well visited at Calcutta for 

 the sake of its freely exposed honey by HYMENOPTERA.

Tapiria hirsuta, Hook. f. is visited by Bibionids and other 

 small flies at Kobo, Upper Assam (25 to 26-U-12). 



Mimosa pudica, Linn. The honeyless flowers open at 

 dawn and fade at midday. They obtain abundant visits for 

 pollen from Apis dorsata (Bardwan, 10-ix-02 ; Banarhat, 

 Duars, 24-viii-07). Apis indica (Bardwan, 10ix-01),and Apis 

 florea (Bardwan , lO-ix-02). The first named has been seen as a 

 visitor in the Malay Peninsula on many occasions.
